We present the results of our photometric and spectroscopic studies of the new eclipsing cataclysmic variable star 1RXS J180834.7+101041 .
Its spectrum exhibits double-peaked hydrogen and helium emission lines .
The Doppler maps constructed from hydrogen lines show a nonuniform distribution of emission in the disk similar to that observed in IP Peg .
This suggests that the object can be a cataclysmic variable with tidal density waves in the disk .
We have determined the component masses ( M _ { WD } = 0.8 \pm 0.22 M _ { \odot } and M _ { RD } = 0.14 \pm 0.02 M _ { \odot } ) and the binary inclination ( i = 78. ^ { \circ } \pm 1. ^ { \circ } 5 ) based on well-known relations between parameters for cataclysmic variable stars .
We have modeled the binary light curves and showed that the model of a disk with two spots is capable of explaining the main observed features of the light curves .
